[PATCH RESEND] xfree86: fix "No devices detected" error for non-seat0 seats (#66851)

[Laércio de Sousa]

Yes, they do, provided you tag another suitable device (e.g. a USB hub) as
"master-of-seat" in udev.

You'll also need to configure the card via custom xorg.conf. In case your
display manager doesn't allow X server command line customization, you can
use Oleg Samarin's patch to introduce new key MatchSeay in xorg.conf.
